I forgot to mention opencl works but is very unstable.CUDA woks brilliantly on same box with win7, speeding up renders 7 times.Problem is I have only 32 bit win7 and fans blow like crazy all the time,even with little or no work going on.In Gentoo however they only go to full power when box is actually doing something other then displaying icons.
Tried again to switch profile, and this time emergeing nvidia-cuda-toolkit and then blender.Toolkit finished but blender spewed out this error:

I have no idea as of where to go from here.So i tried reemerging scons and then blender
that gave me sa,e errors *yeeha*
I am out of ideas and town for now.
So will do emerge -e system with no faith.
